I thought user modifications would already be known at that point.

That would work of course. [jinks@hydra]~ % grep md /proc/partitions 9 0 48064 md0 9 1 72051392 md1 9 2 166818688 md2 The only downside I can see is, that arch *might* activate arrays which are actually used by other Linux system on the same computer, but that shouldn't harm anything.
